We recommend that the diameter of your finished plant be 1.5 to 2 times the pot size. On average, starting with a rooted cutting, a Belgian Mum will grow 1.5" per week. Knowing this, if you want your 6" Belgian Mum to finish with a 12" spread you would need to plant rooted cuttings 8 weeks prior to your desired finish date. You will need to pick your arrival date based on the bloom time of your variety and finished pot size.

Flowering

Garden Mums grown in full sun will have the best quality.

Premature budding occurs when plants initiate flower buds before they reach the reproductive stage due to stressful environmental and growing conditions. This will result in plants finishing short and flowering too early. The following steps could prevent premature budding even if you notice small initiated flower buds on your starting material:

Never allow plants to dry during vegetative stage

Light cuttings during rooting — 4 hours night interruption

Avoid planting/moving outside too early in the North

Feed with phosphor-rich fertilizer at 200-300 ppm right after transplanting to promote vegetative growth

If unable to maintain proper temperature and lighting, apply Florel week before or after transplanting at 500ppm no later than June 20th to avoid flower delays.

Spacing

Spacing will vary from grower to grower depending on finished pot size and your target sales market. For best results, the foliage should never touch. To calculate spacing, a good rule of thumb is to use the expected diameter of the plant plus 2".

Height Control

No growth regulators are needed. Smaller finished products may benefit from the use of growth regulators. B-9 sprayed at 2500 to 5000 ppm will slow the growth. A Bonzi drench at 2-3 ppm will almost completely stop all growth. The last PGR application should be no later than 4 weeks before first color. Excessive or late applications of growth regulators will delay flowering. Florel will not increase branching but is recommended as a foliar spray during rooting and shortly after transplanting outside to prevent premature budding. This treatment is not necessary for indoor finished crops. Florel may not abort existing buds but will prevent formation of new flower buds.

Pests

The most common pests drawn to this crop are Aphids, Mites, Caterpillars, Leafminers, and Thrips.

Disease

Gediflora offers disease free, greenhouse grown cuttings that should perform better than any other mums on the market. Thorough monitoring of your crop, implementing IPM program and prevention are the best defense options against insect and disease problems. Since there is no good chemical control for Bacterial leaf spot and Fusarium, it is very important to use drip irrigation, sterilize production areas, remove weeds and use healthy plant material.

Planting Belgian Mum Mika Orange Liners

Plant deep so the top of our ellepot is slightly below the soil level in your container. It is especially hard to plant deep in a growing media with a high content of pine bark. Slow down the transplant line, and do it right.

Plant in the center. This will eliminate any issue of lopsided, wobbly plants at finish. There is a chance you had 10-15% plugs planted off-center last season.

Rooted Cuttings

Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
